This example demonstrates loading and parsing a CSV file with D3, displaying the file size, row count, and column count as large text. It uses d3.csv to fetch the dataset from a GitHub gist of CSS named colors, then relies on d3.csvFormat and data.columns to compute the metrics. The page is a minimal HTML document with a pre element for output, styled with em-based font sizing, and the visualization updates once the asynchronous data loading completes.
